Lost password

I have contacted Toshiba and becuz there is not a retailer close that can fix this, I am stuck with a laptop I cannot use. I am running Vista, didnt make a backup for my password (had no idea i had too!) now I only got one option, enter the password. I have a black screen with a blue box that says enter password. Now what? I have tried everything and anything I can think of as to what my password is and nothing works. I cannot find a toshiba rep that can help. I cannot find anything online as to what options I have, I cannot even get into the BIOS to try and restore. there is no other options that I can find... HELP!!! I have an HP that I was smart enuff to do a backup on after this mess... but I need this other laptop for school.. any ideas are worth a shot at this point!! Thanks so much for ur time!
